2 Claims.

This' invention relates to a. unit having a pin "stem andcatch therefor; and has for one of its "objects the provision of a solderless unit construction comprising a pin stem,a joint'there'for '5 and catch, all of which may be handled together and-attached to an ornament by solder, riveting or other-means.

Another object of the-invention is the provision 0f asimple' catch and safety device therefor upon such a unit by the folding of a portion of the base of theunit to form the relatively stationary part upon which a rotary safety catch may be mounted.

Another object of the invention is the provision of a rotary safety catch in a simple and inexpensive manner which may be readily manipulated and assembled in position without the use 'ofsolde'r. Another object of the invention is the provisi'on of a safety catch which by reason of an increased and well balanced bearing, the rotary parts will not'readily cramp but will be-s0 supported that the same maybe smoothly and-readily rotated on itsbearing.

Another object-of'the invention is the provision of a catch which-may be of such construction as to entirely protect and'guard the end of the pin stem that the same will not catch or abrade the garment upon which the device is mounted.

A. further object of the invention is the provision of a safety catch which may be rotatably mounted at one end while the other end protrudes to receive and guard the pin stem point.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

It is frequently desirable to provide a unit which may be attached to an ornamentfor the formation of a bar pin' or the like, without the necessity of assembling separate parts upon such ornament and the aligning of these partsithat,

fabric or parts upon which it is mounted; andin,

order'that these results may be accomplishedin' a simple construction I may turn the end of the baror base in such amanner as to form a mounting for the vsafety catch and in some instances to-itself serve asla part of the catch for retaining the pin stem, and in order "thatithe safety catch may havea smooth'action and one which. wiilnot cramp by pressure at one side, I have provided a bearing on either side of the stationary part to better distribute and support pressures which may tend to move the same; and the following is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawing, l5 designates the base or bar of a finding unit, which is pierced as at I6 to providefor attaching the same to a suitable ornament. At one end of this bar a. pair of ears I! are secured by means of fingers I8 extending through the bar and riveted as at l9.

These fingers are integral with the web 20 extending between the ears l1.

also limited in its opening movement by a similar I stop 25 upon the opposite sides of the ears.

Each of these ears has a portion forced inwardly as at 21 to pro- The opposite end portion 26 of the bar I 5 is a folded at generally right angles to the bar and V is shaped to provide a hool;.21 having an entrance opening 28 and a generally circular recess 29 in which the pointed end 30 of the pin Figs. '7, 8 and 9.

stem 23 may be lodged to be maintained under pressure by reason of the resilience in the pin stem 23 and the fiexure thereof over the stop 24.

The receiving opening 29 of this hook forms a bearing for the safety catch, which consists of ears 3! joined together by a bridge portion 32 with each ear having an inwardly extending. portion 33 fitting within the opening 29 and having a bearing therein by which these ears are rotatably supported for movement through an arc otfsubstantially 270.- .The' are :is limited by reason of the bridge and handle portion32 engaging the base of the hook at 34 on one side; or the base at 35 on the other side thereoffas illustrated respectively, in Figs. 3 and-4. M'Aseach; of the ears has this portion extending into. the opening a substantial and well balance'd'bear-' ing is formed which will not become ,JjammEd-bY.

pressure on one side only. These ears are slotted as at 36 so that when the bridge .32 is in the position illustrated in Fig.

4there will be an. opening into the center of the hook, while when this bridge is rotated-to the :position illustrated in Fig. 5, this opening will be closed both by reason of the ear,-the bearing and the bridge portion so that thei'ree end portion of the pin stem cannot escape therefrom.

These ears together with the right angularly extending poitionv 26 of the bar are of suflicient width to completely embrace the pointedportion of the pin stem and prevent the same from catching on or abrading any of the fabric with which thesame comes in contact. i r

;In some instances, I maydesire to uses; different construction such as that illustrated in In this case, the bent or right angular portion of the bar; I5 is designated .31

- and is provided with a cylindrical opening 38 to receive a sleeve portion 39 of the safety catch .:which is enlarged asat .40 .to form'an abut- 'ment 'andhandle bywhich the same may be manipulated. This sleeve'39, whichprotrudes a substantial extent from-its bearing'in the opening 38,"is cut away as at 4| so as, toreceive the pointed portion of the pin stem therein after which this sleeve maybe rotated to cover this pointed portion of the pin stem as illustrated in I45 which has asquareshank' threaded on its corners enabling it to be threaded into an opening 41 in the bar to be retained in place and in aligned position by forcing the stock 48 of the bar, against the flat portion of the shank and thus mounted upon the bar quickly and without the 'use of solder.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the termed the appended claims. i I claim: I
